Because PHP 5.6.40 is end-of-life (EOL), it remains vulnerable to multiple critical issues disclosed since its final release, including: CVE-2024-4577 (Critical - CVSS 9.8):
Many legacy PHP vulnerabilities stem from lower-level memory management errors in the C source code. Unauthenticated attackers can exploit flaws like CVE-2019-9020 by sending malformed payloads to built-in functions (e.g., xmlrpc_decode ). This triggers an out-of-bounds read or a use-after-free state, potentially causing information disclosure or full system compromise. 2. Remote Code Execution (RCE)
